Formula Used

The mortgage payment is calculated using the standard mortgage formula:

M = P [ i(1 + i)ⁿ ] / [ (1 + i)ⁿ - 1 ]

Where:

M = Monthly payment
P = Principal loan amount
i = Monthly interest rate (annual rate divided by 12)
n = Number of payments (loan term in years multiplied by 12)

This formula accounts for the interest on the remaining balance each month, providing an accurate estimate of your monthly payments.

Worked Example

Let's calculate a mortgage payment for a $250,000 loan with a 4% annual interest rate over 25 years.

Principal (P) = $250,000
Annual interest rate = 4% or 0.04
Monthly interest rate (i) = 0.04 / 12 ≈ 0.003333
Number of payments (n) = 25 years × 12 = 300 months

Plugging these values into the formula:

M = 250,000 [ 0.003333(1 + 0.003333)³⁰⁰ ] / [ (1 + 0.003333)³⁰⁰ - 1 ]

M ≈ $1,432.25 per month

This means you would pay approximately $1,432.25 each month for a 25-year mortgage on $250,000 at a 4% interest rate.
